Performance advantage

The CB300R's compact 286cc DOHC four-valve, liquid-cooled, single-cylinder engine is valued among riders for its free-revving, responsive nature. The engine also works extraordinarily well in real-world road-riding conditions, providing plenty of power both around town and out on the highway.

Efficient design

Confidence inspiring

The power of the engine combined with the six-speed transmission produces a remarkably broad torque curve for strong low-rpm performance. This makes the CB300R easy to ride, in both stop-and-go situations and on the highway, while also returning impressive fuel economy.

Efficient engine

The crankshaft runs in plain bearings for quieter operation and the big end of the connecting rod spins in a needle bearing, both contributing to the engine’s high-performance credentials.

Less vibration – more comfort

A gear-driven counterbalance shaft helps quell engine vibration for enhanced rider comfort.

Crisp throttle response

Programmed Fuel Injection (PGM-FI) continuously monitors several variables to ensure the correct fuel mixture for the current riding and atmospheric conditions. The system delivers optimal performance and remarkably crisp throttle response over a wide range of operating conditions, plus improved fuel economy.
